2010-11-01fs: logfs: Fix up MTD=y build.Paul Mundt
Commit 7d945a3aa760 ("logfs get_sb, part 3") broke the logfs build when CONFIG_MTD is set due to a mangled logfs_get_sb_mtd() definition. Signed-off-by: Paul Mundt <lethal@linux-sh.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2010-10-29logfs: fix a leak in get_sbAl Viro
a) switch ->put_device() to logfs_super * b) actually call it on early failures in logfs_get_sb_device() Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

take logfs_get_sb_device() calls to logfs_get_sb() itself Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2010-10-29logfs get_sb, part 2Al Viro
take setting s_bdev/s_mtd/s_devops to callers of logfs_get_sb_device(), don't bother passing them separately Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2010-10-29logfs get_sb massage, part 1Al Viro
move allocation of logfs_super to logfs_get_sb, pass it to logfs_get_sb_...(). Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

logfs does not need the BKL, so use ->unlocked_ioctl instead of ->ioctl in file operations. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Joern Engel <joern@logfs.org> [ fixed trivial conflict ] Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com>

2010-05-07logfs: handle powerfail on NAND flashJoern Engel
The write buffer may not have been written and may no longer be written due to an interrupted write in the affected page. Signed-off-by: Joern Engel <joern@logfs.org>

2010-04-15[LogFS] Prevent mempool_destroy NULL pointer dereferenceJoern Engel
It would probably be better to just accept NULL pointers in mempool_destroy(). But for the current -rc series let's keep things simple. This patch was lost in the cracks for a while. Kevin Cernekee <cernekee@gmail.com> had to rediscover the problem and send a similar patch because of it. :( Signed-off-by: Joern Engel <joern@logfs.org>
2010-04-13[LogFS] Prevent memory corruption on large deletesJoern Engel
Removing sufficiently large files would create aliases for a large number of segments. This in turn results in a large number of journal entries and an overflow of s_je_array. Cheap fix is to add a BUG_ON, turning memory corruption into something annoying, but less dangerous. Real fix is to count the number of affected segments and prevent the problem completely.

2010-03-28[LogFS] Clear PagePrivate when moving journalJoern Engel
do_logfs_journal_wl_pass() must call freeseg(), thereby clear PagePrivate on all pages of the current journal segment. Signed-off-by: Joern Engel <joern@logfs.org>
2010-03-04[LogFS] Only write journal if dirtyJoern Engel
This prevents unnecessary journal writes. More importantly it prevents an oops due to a journal write on failed mount.
2010-03-04[LogFS] Fix bdev erasesJoern Engel
Erases for block devices were always just emulated by writing 0xff. Some time back the write was removed and only the page cache was changed to 0xff. Superficialy a good idea with two problems: 1. Touching the page cache isn't necessary either. 2. However, writing out 0xff _is_ necessary for the journal. As the journal is scanned linearly, an old non-overwritten commit entry can be used on next mount and cause havoc. This should fix both aspects.
